Currently the renesas-irqc driver uses postcore_initcall().

However, the new CPG/MSSR driver uses subsys_initcall(). Hence the
IRQC's probe will be deferred, which causes the Micrel phy to not find
its interrupt on R-Car Gen2, as the of_mdio subsystem doesn't support
deferred probe yet.

Replace postcore_initcall() by device_initcall() to work around this.

This does cause a few extra probe deferrals on R-Mobile APE6, where the
PFC/GPIO combo uses the IRQC as its parent interrupt controller.

Sergei: Does this fix the regression with the sh_eth driver?

   Yes, it does! Thank you! :-)
